What Happened
- Iran launched a large barrage of overnight strikes on Israeli territory, resulting in dozens of casualties and significant damage to residential and civilian infrastructure.
- The strikes involved a combination of ballistic missiles and unmanned aerial vehicles (drones), mirroring Iran's established multi-vector attack pattern first used during the Twelve-Day War (June 2025).
- Israeli air defences intercepted a portion of the incoming projectiles, but numerous missiles breached defensive layers, causing injuries and property damage.
- The strikes were framed by Tehran as retaliation for continued Israeli military operations, including strikes on Iranian-aligned forces and Iranian territory.
- The escalation occurred within the broader context of the ongoing Iran-Israel conflict that began with the Twelve-Day War in June 2025.

Iran–Israel Conflict: Historical Background and Strategic Dynamics
Iran and Israel do not share diplomatic relations and have maintained a state of deep hostility since the 1979 Islamic Revolution, when Iran's new government repudiated the Shah's close ties with Israel. Iran does not recognise Israel's right to exist and has consistently supported organisations — Hamas, Hezbollah, Palestinian Islamic Jihad — engaged in armed conflict with Israel.
- Iran's strategic posture toward Israel relies on a concept of "forward defence" or "axis of resistance" — maintaining a ring of proxy forces (Hezbollah in Lebanon, Hamas in Gaza, Houthis in Yemen, militia in Iraq and Syria) to project pressure on Israel without direct state-to-state confrontation.
- The Twelve-Day War (June 13–24, 2025) marked the first direct, large-scale military confrontation between Iran and Israel, involving Israeli airstrikes on Iranian nuclear and military infrastructure, Iranian missile and drone retaliation, and US strikes on Iranian nuclear sites.
- Iran's nuclear program was significantly degraded during the Twelve-Day War; however, underground facilities at Isfahan survived.
- By early 2026, the conflict entered a second phase as Iran reconstituted some military capacity and resumed hostilities.
Connection to this news: The overnight strikes on Israel represent a continuation of the direct Iran-Israel confrontation that emerged from the Twelve-Day War — a qualitative shift from the earlier proxy-based conflict model.
Ballistic Missiles and Drone Warfare: Technology and International Law
Modern conflicts increasingly feature dual-use of ballistic missiles and unmanned aerial systems (drones) as complementary strike packages. Iran possesses one of the largest ballistic missile arsenals in the Middle East, developed indigenously due to decades of international sanctions limiting conventional weapons imports.
- Iran's ballistic missile arsenal includes short-range, medium-range, and intermediate-range missiles; key systems include the Shahab series, Fateh series, and the Fattah hypersonic missile (claimed to be introduced in 2023).
- Shaheed-series attack drones (one-way kamikaze drones) have been widely used by Iran and its proxies since 2022-23; they are relatively inexpensive and difficult to intercept in large numbers.
- Israel's multi-layered air defence system — Iron Dome (short-range), David's Sling (medium-range), Arrow-2 and Arrow-3 (long-range/exo-atmospheric) — is among the most sophisticated in the world but has limits against saturation attacks.
- Under international humanitarian law (IHL), attacks must distinguish between military and civilian targets (principle of distinction) and must be proportionate (principle of proportionality).
Connection to this news: Iran's use of combined ballistic missile and drone barrages is designed precisely to saturate multi-layered defences — a strategy that even advanced systems like Arrow-3 cannot fully counter when attack volumes are sufficient.
Non-State Actors and State Responsibility in International Law
When a state uses non-state proxies to conduct attacks, the question of state responsibility arises. The International Court of Justice (ICJ) and the International Law Commission (ILC) have developed frameworks for attributing the acts of non-state actors to states.
- The Nicaragua v. USA case (ICJ, 1986) established the "effective control" test — a state is responsible for acts of non-state actors only if it exercises effective control over those specific acts.
- The Tadic case (ICTY, 1999) established a looser "overall control" test applicable in armed conflict contexts.
- Iran's direct strikes on Israel, by contrast, attract straightforward state responsibility under the UN Charter's Article 2(4) prohibition on the use of force against territorial integrity.
- UN Charter Article 51 preserves the right of self-defence in response to armed attacks — both sides have invoked this provision.
Connection to this news: Iran's direct strikes (as opposed to proxy strikes) simplify the legal attribution question — they constitute a direct use of force triggering Article 51 self-defence rights under the UN Charter.
